			<h3>Three unequal columns</h3>
			<p>Get three columns starting at desktops and scaling to large desktops of various widths. Remember, grid columns should add up to twelve for a single horizontal block. More than that, and columns start stacking no matter the viewport.</p>

			<h3>Full width, single column</h3>
			<p class="text-warning">No grid classes are necessary for full-width elements.</p>
			
			<hr>
			<h3>Two columns with two nested columns</h3>
			<p>Per the documentation, nesting is easy—just put a row of columns within an existing row. This gives you two columns starting at desktops and scaling to large desktops, with another two (equal widths) within the larger column.</p>
			<p>At mobile device sizes, tablets and down, these columns and their nested columns will stack.</p>

			<h3>Mixed: mobile and desktop</h3>
			<p>he Bootstrap 3 grid system has four tiers of classes: xs (phones), sm (tablets), md (desktops), and lg (larger desktops). You can use nearly any combination of these classes to create more dynamic and flexible layouts.</p>
			<p>Each tier of classes scales up, meaning if you plan on setting the same widths for xs and sm, you only need to specify xs.</p>
